目的了解延边地区2011~2015年食品中主要食源性致病菌的污染状况,确定高危食品,为预防和控制食源性疾病提供科学依据。方法利用国标方法及《2013年国家食品污染物和有害因素风险监测工作手册》对2011~2015年在延边地区采集的1069份食品样品进行沙门氏菌、单核细胞增生李斯特菌、金黄色葡萄球菌、铜绿假单胞菌和蜡样芽孢杆菌等的监测。结果 1069份样品中共检出致病菌115株,总检出率为10.76%。熟肉制品、生食动物性水产品、凉拌菜、熟制米面制品、婴幼儿食品、乳及乳制品、速冻米面制品、特殊膳食用食品、饮用水、三明治以及流动早餐样品的致病菌检出率分别为17.65%(3/17)、15.79%(3/19)、11.76%(4/34)、34.48%(10/29)、33.80%(24/71)、40.00%(12/30)、6.67%(1/15)、42.86%(6/14)、58.33%(7/12)、10.00%(1/10)和71.43%(10/14);其中2013年的总体检出率最高,达6.83%,其次是2012年,达1.87%。结论乳及乳制品、特殊膳食用食品、饮用水和流动早餐是延边地区的主要污染食品,作为直接入口食品的熟肉制品、凉拌菜、熟制米面制品和婴幼儿食品可能导致较高的食源性疾病风险。
Objective To understand the pollution status of food-borne pathogens in Yanbian area from 2011 to 2015, and to identify high-risk foods to provide scientific basis for the prevention and control of food-borne diseases. Methods A total of 1069 food samples collected from Yanbian area from 2011 to 2015 were analyzed by Salmonella, Listeria monocytogenes, Staphylococcus aureus, Staphylococcus aureus, Staphylococcus aureus, Pseudomonas aeruginosa and Bacillus cereus and other monitoring. Results A total of 115 pathogenic bacteria were detected in 1069 samples with a total detection rate of 10.76%. Cooked meat products, raw animal-based aquatic products, cold dishes, cooked rice products, infant food, milk and dairy products, frozen rice products, special dietary foods, drinking water, sandwiches and mobile samples of the breakfast pathogen detection The rates were 17.65% (3/17), 15.79% (3/19), 11.76% (4/34), 34.48% (10/29), 33.80% (24/71), 40.00% (12/30) , 6.67% (1/15), 42.86% (6/14), 58.33% (7/12), 10.00% (1/10) and 71.43% (10/14) respectively, of which the overall detection rate was the highest in 2013 , Up 6.83%, followed by 2012, up 1.87%. Conclusions Milk and dairy products, special dietary foods, drinking water and mobile breakfast are the major contaminated foods in Yanbian. Cooked meat products, salad dressing, cooked rice noodles and baby food products as direct entry foods may cause higher food intake Source disease risk.
